TO ALL PERSONS T0 WHOM THES-PRESENTS SHALL COME:

Be it known that I, ALBERT I-I. GIIMAN, ofHopedale, in the county of Worcester, and State of Massachusetts, have made a new and useful invention having reference to Spinning-Spindles and Vthe caps of their steps; and I do hereby declare the same to be fully described in `the following specification and represented in the accompanying drawings,`of `whch i Y Figure l is an elevation; and

Figure 2, a longitudinal section of a spindle, its step and cap provided with my invention.

The nature of `my invention consists in the application of the step-capot' cover to the spindle by means or devices such as, when the capI maybe encompassing or covering the step and the spindle may be in revolution,

shall not only cause 4the cap to bel revolved with the spindle, but allowiit, the said cap, to be freely raised off the step in order to enable such step to be supplied with oil, as occa-sion may require. VIt further consists in' the combination and arrangement ofa collar with the spindle andthe lcap, to beiarrzangedpwith a step, as set forth.

It further consists in the arrangement of a collar and a stud` with the spindleV andfcap provided with a` recess to receive the stud and to be appliedto a step, as hereinafterY explained". The, objects ofmy invention `are to enable the cap to be raised off the step in order that the latter may be supplied with oil while the spindle may bein revolution; also, to prevent dirt and waste that may work down betweenl the crap and ,the spindle from dropping into the step. i i p v i i' l In the drawings, A denotes the spindle; B its step; a, the `bushing of the stepyvb the'l point of the spindle, and C the cap of the step. The cap encompasses the spindle and slides freely and down thereon. When down to its lowest position it eneircles and covers the upper part of the step and rests on a collar or annnlus, D,'ixed dn the spindle concentrically, and having a cliameter-equal or about equal to that of the larger part of ithe bore of the cap.` A hole, c, is bored vertically in the cap to receive a pin or s'tud, d, extending upward from the collar. The purpose of the stud and hole is to so clutch the cap to thespindle when the cap is resting on the collar that the cap will revolve with thespindle. As a substitute for the 'stud and ,holexa leather washer, placed on the collar and around the spindle, could be used, but not to so good'advantage.` The collar, `besides serving as a support for the cap, answers as a protector of the step against dust, waste, or extraneous matters, such as are liable to work down between the cap and the spindle when they are in use, land the former is so applied to the latter as to be capable of' being freely moved up and down thereon. In the commen application of the cap to the spindlel the former is fastened to the latter by meansI of a screw orotherwise, so that whileithe spindle may be in revolution the cap cannot be raised thereon in order to allow oil to be poured into the step, but with my invention or improvement the cap can be raised whilethe spindle may be in rotation, and on being droppeddown to its position to cover 'the step will revolve with and be revolved by the spindle. Even werethe cap to rest on 'the step and not rotate with the spindle the collar Dfwill Astill serve as a protection to' the step, and in manner as hereinafter explained.

I claim as my invention the following, that is to say- I claim the application of the step-cap C to the spindle A by means or devices such as, when the capmpay be encompassing or covering the step, and' the spindle may he in revolution, shall not only cause thel cap to be -revolved with the spindle, but allow it, the said cap, to be freely raised off the step in order to enable such step to be supplied with oil as occasion may require.

I also claim the combination and arrangement of the collar. D with the spindle A and the cap, arranged with a step, as set forth, the collar being for the purpose or objects as explained. Y I

I also claim the arrangement of the c'ollarD and the stud d with the spindle A and the cap C, provided with a Arecess or hole, c, to receive the stud, and applied to a step, B, substantially as described.

ALBERT H. GILMAN.
